“…The latter species uses it both as food and as a preferential location for egg laying (Capy & Gibert, 2004;Forsander, 1998;McKenzie & McKechnie, 1979;McKenzie & Parsons, 1972, 1974. Furthermore, D. melanogaster has increased fitness on food containing ethanol (Parsons & Spence, 1981). This is presumably because ethanol sanitizes the food by inhibiting or killing harmful microbes-an application of ethanol also used by humans.…”

“…Nevertheless, the concentration of such volatiles is important (Zhu et al ., ). Drosophila melanogaster is attracted to high concentrations of ethanol from fermenting fruit, whereas Drosophila simulans and Drosophila immigrans are sensitive to and inevitably avoid high doses of ethanol (Parsons & Spence, ). Hence, the olfactory system in these species is adapted to their environment.…”

Olfactory responses of Drosophila suzukii females to host plant volatiles

et al. 2015

Drosophila suzukii Matsumura, an endemic pest in southeast Asia, has invaded Europe and the U.S.A. Unlike most of its closely related sibling species, the serrated ovipositor of D. suzukii permits ovipositing in undamaged fresh fruits. In the present study, volatiles are identified from host plants that are potentially involved in D. suzukii host recognition and oviposition behaviour. It is shown that mated females are attracted to volatiles emitted from intact fruits. The antennally‐active suite of compounds released from the fresh fruits is identified by gas chromatography coupled with electroantennographic detection, as well as gas chromatography‐mass spectrometry. In olfactometer bioassays, mated females are significantly attracted to an electroantennographically active volatile, isoamyl acetate, when tested at 10 µg of synthetic compound in a rubber septa, which has a release rate comparable to that of fresh fruits. In addition, a genomic survey shows that D. suzukii not only possesses the full repertoire of genes encoding odorant receptors activated by isoamyl acetate in D. melanogaster, but also that one of the genes, OR67a, is represented by five duplicated copies. These results indicate that D. suzukii uses olfactory cues to select oviposition sites. The identification of volatiles emitted by host fruits that attract D. suzukii may aid in the development of a selective and efficient synthetic lure for monitoring this pest. As a close relative of Drosophila melanogaster, D. suzukii provides a unique opportunity for understanding the physiological mechanisms involved in the shift of this species from use of rotten to ripe fruits for oviposition.

“…Both the changes in oviposition depression and ethanol food preference elicited by the wasp require an intact Drosophila visual system (Kacsoh et al 2013). Drosophila larvae and adults in particular derive benefit from consumption of low concentrations of ethanol by converting ethanol to energy stores, increasing development speed, and increasing overall longevity (Chawla et al 1981;Parsons 1981;Geer et al 1985). However, at higher ethanol concentration (.4%), D. melanogaster larval development is protracted and flies suffer from increased mortality (McKenzie and McKechnie 1978;Chawla et al 1981;Parsons 1981;Geer et al 1985).…”

A Novel Paradigm for Nonassociative Long-Term Memory inDrosophila: Predator-Induced Changes in Oviposition Behavior

et al. 2015

Learning processes in Drosophila have been studied through the use of Pavlovian associative memory tests, and these paradigms have been extremely useful in identifying both genetic factors and neuroanatomical structures that are essential to memory formation. Whether these same genes and brain compartments also contribute to memory formed from nonassociative experiences is not well understood. Exposures to environmental stressors such as predators are known to induce innate behavioral responses and can lead to new memory formation that allows a predator response to persist for days after the predator threat has been removed. Here, we utilize a unique form of nonassociative behavior in Drosophila where female flies detect the presence of endoparasitoid predatory wasps and alter their oviposition behavior to lay eggs in food containing high levels of alcohol. The predator-induced change in fly oviposition preference is maintained for days after wasps are removed, and this persistence in behavior requires a minimum continuous exposure time of 14 hr. Maintenance of this behavior is dependent on multiple long-term memory genes, including orb2, dunce, rutabaga, amnesiac, and Fmr1. Maintenance of the behavior also requires intact synaptic transmission of the mushroom body. Surprisingly, synaptic output from the mushroom body (MB) or the functions of any of these learning and memory genes are not required for the change in behavior when female flies are in constant contact with wasps. This suggests that perception of this predator that leads to an acute change in oviposition behavior is not dependent on the MB or dependent on learning and memory gene functions. Because wasp-induced oviposition behavior can last for days and its maintenance requires a functional MB and the wild-type products of several known learning and memory genes, we suggest that this constitutes a paradigm for a bona fide form of nonassociative long-term memory that is not dependent on associated experiences.KEYWORDS Drosophila melanogaster; learning and memory; long-term memory; behavior A fundamental trait that higher-order organisms possess is the ability to remember and recall past experiences. This wonderful ability of higher organisms to remember past experiences is observed in all animals and therefore drives intense interest to elucidate the molecular underpinning of learning and memory in model systems, such as Drosophila. Insight into the biology of memory has been gained with a wide array of experimental approaches ranging from behavioral phenomena and underlying physiological correlates to experimental interventions such as pharmacological, biochemical, and anatomical perturbations in model genetic systems. Genetic manipulations also provide key insight into behavioral plasticity, as this approach allows us to understand the genetic components regulating this plasticity while providing clues into the extent of evolutionary conservation among the different molecular mechanisms governing this plasticity (Greenspan 1995).Drosophila...
